Skier’s thumb physical therapy in Carmel, Indiana

When you fall with a ski pole strap around your hand, the pole levers the thumb backward and away from the hand. That stresses the ulnar collateral ligament, which runs along the inner side of the thumb knuckle (the metacarpophalangeal joint) and stops the thumb from bending sideways.

Skiing is the classic setting, which is why Indiana skiers often bring the injury home from a trip west or north. But the same mechanism happens with a fall on ice, a basketball or volleyball jammed into the thumb, a goalkeeper’s save, a bike crash on the handlebars, or a missed catch in softball. The older name, gamekeeper’s thumb, described a chronic loosening of the same ligament from repeated strain.

Sometimes a small piece of bone is pulled off with the ligament, called an avulsion fracture. That changes the treatment and is one reason an X-ray is often ordered after a thumb injury. A displaced fragment usually needs a surgeon, while a small fragment that stays in place may heal in a cast much like a partial tear.

Partial tears and stable injuries are usually treated by holding the thumb still in a thumb spica cast or splint for several weeks, with the rest of the hand free; the physician sets the length. The goal is to let the ligament heal at the right length so the thumb is stable for pinching.

Physical therapy usually starts with gentle motion once the physician allows, while the thumb is still protected by a removable splint between exercises. Stress on the healing ligament, such as hard pinching or pulling the thumb sideways, is avoided at first.

Later, therapy builds pinch and grip strength with putty, clothespins and light weights, then progresses to sport and work demands: catching, gripping a pole or racket, holding tools. Some therapists use a small orthosis or taping when you return to sport.

Throughout, the rest of the arm is kept strong. Shoulder, elbow and forearm work can continue in the suite with the thumb protected, so that when the splint comes off you are only rebuilding the thumb, not the whole upper limb. Cardio and lower-body training usually carry on almost as normal.

• Protection: cast or splint for several weeks, finger and wrist motion kept up.
• Early motion: gentle thumb motion out of the splint once the physician allows.
• Strengthening: pinch and grip work, with the splint coming off for daily tasks.
• Return: unrestricted use and sport once the thumb is stable and strong, often with protective taping.

Ice the thumb, keep the hand raised, and avoid pinching or gripping with it. Do not try to test how loose the thumb is by pulling on it. Arrange an assessment within a few days, especially if the thumb feels unstable, has a lump on the inner side, or bruises heavily.

Indiana allows you to see a physical therapist first, and a therapist can help sort out whether you need a physician or hand surgeon urgently. For other wrist injuries from the same fall, compare with wrist sprain.
